1 To all wkomct may concern: r Be it known that I, BENJAMIN A.

HUGHES, a citizen of the United States, re-- sidingat Colorado Springs, in the county of El Paso and State of Colorado, have inrented certain new and useful Improvements. in Machines for Sizingand Separating Granular Material, of which the fol-v lowing is a specification, reference being had to the accompanying drawings.

"This invention relates to .machines for a sizing-and separating granular material and has for its object to produce a machine of this character Which'is-simple in construction, durable and efficient in operation and 1 one Which may be manufactured cheaply.

.A further object of the invention is to produce a machine 'of this character provided With a pair of hingedly. connected and'adjustable rifiie decks said decks being adapted to be adjusted at'jdifferent inclinations. Y

A still further object of .the invention-is to construct a machine of this character With anew and novel arrangement 'Of tog- .gle connection between the reciprocating upper frame andstationary-lower frame,

, .VVith the above and other objects'in view,-

-- thislinvention resides in the novel features 30.0f construction, combinationand arrange ment of parts as will be hereinafter more fully described, claimed, and illustrated in the-accompanying drawings, in which,

Figure 1 is aside elevation of a machine embodying this invention, with parts 'refmoved in order to show the end and interior parts of the machine. 'Fig. Zis anend v elevation of the machine proper. Fig. 3 is a topplan View of one, of the rifile decks, lines 40 being indicatedthereon in order to show the direction of the; material. across the same- Whenthe machine ismperated. Fig. 4 1s a sectional View along the line 4-4 of Fig. 5 and in addition showing the connecting '45 parts of the riflle deck of the framework of the machine. Fig. 5 is a plan view with the riflie decks removed. Fig. 6 is a section along the line 66 of-Fig. 3. Fig. 'Z is a section along theline 77 of Fig.3.

Similar reference characters refer to'simif lar parts throughout the drawings.

, Referring to the drawings, the numeral 1 design'ates,in general, the deck supporting Y frame, the same consisting of end $1115 2 and side sills 3. Mounted for sliding niovement upon each end sill 2 are a pair of oppositely Specification of Letters Patent. Patented Sept. 24, 1912. .Application filed November'S, 1911. Serial No. 659.158.

disposed plates 4:, each of ivhich is provided at its inner end'with an upwardly extending flange 5, said'flanges being formed with aline'd threaded openings 6, and in which are threaded the opposite ends of screwbolts 7. 1 The threaded ends of said bolts are oppositely threaded, as clearly shown in Fig. 5 of the drawings.

The plates 4: are each provided with a pair of off-set slots 8 and through which pass b'olts '9, said bolts being also passed through suitable openings formed in the end sills 2, whereby the plates 4 may be adjusted toward or away from each other. It

will be noted that theintcrmediate portion of thescrew bolts 7 are not threaded and are supported at this point by a right angle bracket 10, said bracket being provided with an aperture 11 and in which the bolt 7 is rotatably mounted.

Rigidly secured to the unthreaded portion of the bolt -7' and -adjacent the right angle bracket lOisa hand Wheel 12, which, when operated, will rotate the threaded bolt 7 to adjust the plates 4,-as desired. The outer ends of the platesl are so bent as to forin inafter described.

The bottom "or supporting frame 14: is formed ina manner similar to the frame 1 and isof substantially the same width. and

' eyes 13,-the purposeof which will be hereconsists of end sills 15 and side sills 16. In-

termediate the end sills 15 is a transversely arranged brac'e 17, the same having its opposite'ends suitably: connected to the side sillslti. The brace 17 is provided at its center with a horizontally arranged opening l8 and in which is clamped the eye bolt it). The frame 1 is fleiribly supported above the frame lfby toggle joints 20, said joints heing-arranged between the "end sills 2 of the upper-frame and end sills 15 of the lower frame, said joints being connected at their upper andlower ends to the sills 2 and if, respectively.

Secured to 'the'under sides of the sills l is an angle *strip 21, said strip being of the same width as the end sills 2. Similar strips 22 are mounted and secured upon the upper faces of the end'sills 15 of th'elower frame 14:. Bolted to the inner faces of the strips 21 and 22 are'vertical clamping plates 23.

Strips 24, preferably formed from rubber and the \Jerl'ieal plates 23 and their lower edges clamped between the angle plates 22 and vertical plates 23. Thestripsof belting 2% are substant ally the-same length as the 7 upperand lower' sills 2 and 15, respectively.

To prevent buckling and atthe same time to allow a free hinge action between the upper and lower frames are a p'aiir'*:'of metallic plates 25, said plates being bolted to that portion of the strip 24 between the angle plates 21ya'nd 22. It will,'ofcourse, be understood. that both strips 24' are provided with the-plates 25. 1 Y

" Passing through an opening 26 formed in i one of the end sills 2 ofthe'upper frame is a cent the" frame lnby a supportin operative position to the upper frame :1.

The 'cam' wheel 29 is rigi lyseeured to a transversely arranged shaft. 32 andT'toone end of which is connected a fixed belt pulley 33 and a loose pulley 34:, both ofwhichbeing which passes around .35

' the upper terminal of the'co'il Tspring36. A

.of the'u sual construction and operating in a manner to drive the cam wheel 29 by the belt r the pulley .33 oridler 34,- as desired. 1

Pivotally eonnected'to-the eye bolt 19 is the lower end of a link 35, the upper endof which'is attached to the lowerte'rininal of a coil-spring 36. Secured to the inner face of one of the sills 2 of the upper frame and intermediate its ends is an angle plate 37,- the same being provided with a screw threaded opening 38 and through which is threaded the threaded upper end of aq bolt 39,- the lower or inner end of which is attached to nut 40 is mounted upon the outer threaded end of the bolt 39, which when, operatedregulatesthe tension of the spring 36,.

Mounted upon the sill 2 "of :the upper frame-and upon the upper face thereof are a pair of bufi'ers41, said buffers acting in conjunction with a pair of'bumpers- 42, said bumpers beingadjustably mounted'near the upper ends of bumping posts 43., Each bumping post 43- is formed near its upper. end with-openings 44 and in which-are inserted internally screw threaded bushings as. The bumpers 42 have projecting from their outervfaces' screw threaded shanks 46,. the extreme outer ends of whichare square whereby the same may be operated upon by a wrench or suitable tool to obtain the proper adjustment: of same.

The cam bolt 27 is adjustable'in the man'- ner as hereinbefore described and is held in its adjusted position by clamping nuts 4'7 arranged upon the inner and outer faces of the sill 2, This arrangement of the cam bolt '27 permits thefadjust-ment of'the same to takeiup the wear due to constant use and 7 caused by the contact of the .cam' wheel 29 .1

with the beveled edge 28 thereof. Alike object is" gainedby the arrangement and ad- I justmentjof the bumpers 42. a

. Supported, bove'the frame 1 are a pair of inclined riflief decks-'48, the upper edges of Y which are, connected by strap hinges 49, said hingbs-being-secured' to the under surface-of each deck; The, rifiie-decks 48 arepivotally connectedto the frame'l, by plates 50, said plates corresponding in numberto the plates 4, mounted upon: the end sills 2 of the frame 1. The plates 50'are each provided at their lower ends"with oppositely disposed ears 51,

said ears being provided with-perforations 52 through whichpivot bolts .53 a repassed when" said-"perforations register with the e'yes13 formed upon'the outer ends of the -'-plates -4=. The-riflle decks 48 areeach provided upon their under surfacewith a plu-. 1 rality of lo itudinally arranged truss'bars Z54; -'Ihe dec 'riflies 48 are'e ac'h of a Sufii.'

,cient width tolhave their lower edges pro-' .ject ed Slightly beyond the side sills of the upper and lower frames so that the material passing thereover will'clea'r the same.

An upright 55 j 1 frame :56, one end'of said frame belng arismounted adjacentthejj ends'of the frames and said upright ispr0' ivided' at itsu'pper end; with a supporting ranged directly over andnea'r' one end of the iueeting upper edges of the riflle decks48.

Mounted in the frame 56 is a hopper 57, said hopper being provided with. a neck"58,' said neck leading to a. spout 59. Mountedin the neck; is regulating'yalve (SQ-whereby the flow of material from the hopper 57 to' the bafiie d'ec-ks may be regulated or flow cut oif entirely. I

The 'riflie deeks, this instance, differfrom the usual separators and sizers inas-- much as the same comprise solid backs in' lieu of theusual screen mesh separators .The. deck backs 61 are formed preferably from-wood and'have arranged on their inner ordeck faces a plurality of diagonally arranged and alined diamond-shaped teeth 62,

each tooth being spaced a sufficient distance apart-to provide a space betweeneach toothv to permit the materialtobe sized or separated to. travel in a direction across the decks diagonally opposite to the line of arrangement of the teeth. Arranged between each line of teeth are 'a' series of channels 63. It will be. noted by arranging the teeth inthis manner that the upper apex of tooth 62"is positioned so that themateri'al falling therefijo be projected upon the succeeding tooth v a pointbetween its upper and lower apexes; so that the fine and coarse material will begraded orseparated and the finer material, which is naturally l ght Wlll be directed toward the upper apex of each tooth and th eco arser materialbemg heavler Wlll drop toward the lower apex of each tooth, and from thence into the channels 63 as the material travels-in a substantially diagonal direction across'each ritfie 1o deck; The coarse material will pass from one tooth to' the other in a diagonal direction toward the lower edge'of the'riflie deck and from the channels to a suitable receptacle arranged for their reception. The finer material also travels in a diagonal direction across the decks and is actedup'on by the teeth in such a manner as to be projectedon the end of the riflie; deck at the end opposite from its point of flow. 'This action'and travel of the material is caused by the continued reciprocation of the frame 1 which consequently causes the longitudinal reciprocation of said decks, the end thrust caused by the reciprocation of these'parts causing the material toflow or beprojected in a rearward direction uponrthe forward and" quick movement of' the frame and decks, during which movement the finer material will in effect jump from the upper ini so clined plane of each tooth'to' the other and the coarser material to have the same action to a certain extent from the 'upperinclined 'plane of one tooth to the sideinclined plane of the succeeding tooth, thussizing the fine and coarse material, it being, of course, un

derstood that certain of the fine material will pass with the coarse material to a certain distance in a downward and diagonal direction until somewhat below the longi- 40 tudinal centerof the deck ritfies.

The general 'constru'ctionjof. the decks is as follows :The decks are -first finished smooth with alplanesurface, and can be of I metal, or tongued and grooved boards iaclosely fitted together. This surface is then covered with linoleum or someother suitable material. After the-cover is secured-to the decks-{lines are drawn acrossthe same and preferably in a transverse dlrectio nof about with-the longitudinal direction 'of the same. As only two faces of these diamond blocks are used in the operation of the machine, they can readily be-made from sheet 6 metal, and if desired integrally with the strip placed thereon to strengthen them.

The size and number of the teeth may bef varied to suit'difierent classes ofwork.

w; Upon rotary movement-being imparted. 510 the shaft 32, the cam wheel 29 is caused' mounted: on the reclprocating decks being pivotally connected near their to rotate which, in; turn, operates the cam bolt 27 to vibrate or reciprocate the upper frame 1, the end thrust of said frame beingregulated by the adjustment of the cam bolt 27, said frame being returned. with a jerk by the coil spring 37 for further action by the cam wheel, the toggle joints to a certain extent imparting in addition to the longitudinal movement .a slight'npward movement to the frame '1 and riflle',decks 4.8, '75 which action dislodges the material and at the same time projects the same in a rearward direction or in a direction opposite to the end thrust. 1

By providing the plates 25 upon the belting 24, the same is braced or reinforced at f its entire width and length between the upper and lower brackets'Ql and 22, respectively, which will not only prevent buckling of the belting 24 but will prevent any-lat-- era-l movement of the upper frame and deck rittle and at the same'time provide a durable and sensitive toggle arrangement between the-upper and lower frames.

, The inclination of the riflie decks maybe 7 adjusted upon operation of the handle wheel 12 to suit different classes'of work as in the process of sizing or separating'cereals or grains the travel would necessarilyhave to be retarded to some extent to allow perfect separation, and in this instance the inclination of the decks will necessarily 'be greater than in cases where crushed ore is being separated or sized, the process being naturally quicker; j

It is a well known fact that finer graded material will adhere or will be frictionally held upon the surface where the coarser material will immediately pass thereover and the dislodging' of the fine materialis greatly enhanced .upon the buffers v41 coming'. in contact with the bumpers 4:2.

The machine isparticularly adapted for. sizing and classifying crushed ore, grain,- sand, and, in fact, any granular material in 1 its dried condition, the different uses being governed by the size and spacing of the. teeth 62 and channels 63.
